Abstract: Using styrene and divinylbenzene as the polymer matrix and sodium bis(2-ethylhexyl) sulfosuccinate (AOT) as the surfactant, we have prepared highly cross-linked porous polymer resins with reverse micellar imprints. The pore size of the polymers was controlled by varying the amount of water in the AOT reverse micelles prior to polymerization. To study the factors that may affect the porosity of the polymers, several series of resins were prepared by systematically varying the surfactant concentration, the degree of cross-linking, and the amount of added cosurfactant. The BET gas adsorption experiments showed that the surface area and pore volume were influenced by the size of the micelles and the surfactant concentration, with maxima near an AOT concentration of 0.2 M. The degree of cross-linking was also found to have an effect on the surface area, pore volume, and even the pore size, but the addition of a cosurfactant, n-butanol, did not affect the porosity of the polymers. The porosity parameters of the polymer resins were found to remain stable after prolonged heating at elevated temperatures
